In various embodiments, at least one of the components (e.g., the connecting terminal 178) may be omitted from the electronic device 101, or one or more other components may be added in the electronic device 101. In various embodiments, some of the components (e.g., the sensor module 176, the camera module 180, or the antenna module 197) may be implemented as a single component (e.g., the display module 160).

The processor 120 may execute, for example, software (e.g., a program 140) to control at least one other component (e.g., a hardware or software component) of the electronic device 101 coupled with the processor 120, and may perform various data processing or computation. According to an embodiment, as at least part of the data processing or computation, the processor 120 may store a command or data received from another component (e.g., the sensor module 176 or the communication module 190) in volatile memory 132, process the command or the data stored in the volatile memory 132, and store resulting data in non-volatile memory 134.

The communication module 190 may include one or more communication processors that are operable independently from the processor 120 (e.g., the application processor (AP)) and supports a direct (e.g., wired) communication or a wireless communication. According to an embodiment, the communication module 190 may include a wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module 194 (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules may communicate with the external electronic device via the first network 198 (e.g., a short-range communication network, such as Bluetooth™, wireless-fidelity (Wi-Fi) direct, or infrared data association (IrDA)) or the second network 199 (e.g., a long-range communication network, such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., LAN or wide area network (WAN)). These various types of communication modules may be implemented as a single component (e.g., a single chip), or may be implemented as multi components (e.g., multi chips) separate from each other. The wireless communication module 192 may identify and authenticate the electronic device 101 in a communication network, such as the first network 198 or the second network 199, using subscriber information (e.g., international mobile subscriber identity (IMSI)) stored in the subscriber identification module 196.

The wireless communication module 192 may support a 5G network, after a 4G network, and next-generation communication technology, e.g., new radio (NR) access technology. The NR access technology may support enhanced mobile broadband (eMBB), massive machine type communications (mMTC), or ultra-reliable and low-latency communications (URLLC). The wireless communication module 192 may support a high-frequency band (e.g., the mmWave band) to achieve, e.g., a high data transmission rate. The wireless communication module 192 may support various technologies for securing performance on a high-frequency band, such as, e.g., beamforming, massive multiple-input and multiple-output (massive MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna. The wireless communication module 192 may support various requirements specified in the electronic device 101, an external electronic device (e.g., the electronic device 104), or a network system (e.g., the second network 199). According to an embodiment, the wireless communication module 192 may support a peak data rate (e.g., 20 Gbps or more) for implementing eMBB, loss coverage (e.g., 164 dB or less) for implementing mMTC, or U-plane latency (e.g., 0.5 ms or less for each of downlink (DL) and uplink (UL), or a round trip of 1 ms or less) for implementing URLLC.

The antenna module 197 may transmit or receive a signal or power to or from the outside (e.g., the external electronic device) of the electronic device 101.

The signal or the power may then be transmitted or received between the communication module 190 and the external electronic device via the selected at least one antenna. According to an embodiment, another component (e.g., a radio frequency integrated circuit (RFIC)) other than the radiating element may be additionally formed as part of the antenna module 197.

According to various embodiments, the antenna module 197 may form a mmWave antenna module. According to an embodiment, the mmWave antenna module may include a printed circuit board, a RFIC disposed on a first surface (e.g., the bottom surface) of the printed circuit board, or adjacent to the first surface and capable of supporting a designated high-frequency band (e.g., the mmWave band), and a plurality of antennas (e.g., array antennas) disposed on a second surface (e.g., the top or a side surface) of the printed circuit board, or adjacent to the second surface and capable of transmitting or receiving signals of the designated high-frequency band.

At least some of the above-described components may be coupled mutually and communicate signals (e.g., commands or data) therebetween via an inter-peripheral communication scheme (e.g., a bus, general purpose input and output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)).

According to an embodiment, commands or data may be transmitted or received between the electronic device 101 and the external electronic device 104 via the server 108 coupled with the second network 199. Each of the electronic devices 102 or 104 may be a device of a same type as, or a different type, from the electronic device 101. According to an embodiment, all or some of operations to be executed at the electronic device 101 may be executed at one or more of the external electronic devices 102, 104, or 108. For example, if the electronic device 101 should perform a function or a service automatically, or in response to a request from a user or another device, the electronic device 101, instead of, or in addition to, executing the function or the service, may request the one or more external electronic devices to perform at least part of the function or the service.

FIG. 2A is a diagram illustrating an example configuration of an electronic device 200 (e.g., the wearable device 101 in FIG. 1 ) including a plurality of cameras according to various embodiments.

In various embodiments, the electronic device 200 may include an electronic device 200 manufactured to be worn, for example, on a user’s head. For example, the electronic device 200 may be constructed, but is not limited to, in the form of at least one of glasses, goggles, a helmet, or a hat. According to an embodiment, the electronic device 200 may include a plurality of transparent members (e.g., a first transparent member 220 and/or a second transparent member 230) respectively interlocking the user’s both eyes (e.g., left and/or right eyes).

The electronic device 200 may provide an image related to an augmented reality (AR) service to the user. According to an embodiment, the electronic device 200 may project or display a virtual object on the first transparent member 220 and/or the second transparent member 230, thereby allowing at least one virtual object to be superimposed on reality that the user perceives through the first transparent member 220 and/or the second transparent member 230 of the electronic device 200.

With reference to FIG. 2A, the electronic device 200 according to an embodiment may include a body part 223, support parts (e.g., a first support part 221, a second support part 222), and hinge parts (e.g., a first hinge part 240-1, a second hinge part 240-2).

According to various embodiments, the body part 223 and the support parts 221 and 222 may be operatively connected through the hinge parts 240-1 and 240-2. The body part 223 may have a portion formed to be at least partially mounted on the user’s nose.

According to various embodiments, the support parts 221 and 222 may include a support member having a shape that can be put over the user’s ear. The support parts 221 and 222 may include a first support part 221 mounted on the left ear and/or a second support part 222 mounted on the right ear.

According to various embodiments, the first hinge part 240-1 may connect the first support part 221 and the body part 223 so that the first support part 221 is rotatable with respect to the body part 223. The second hinge part 240-2 may connect the second support part 222 and the body part 223 so that the second support part 222 is rotatable with respect to the body part 223. According to an embodiment, the hinge parts 240-1 and 240-2 of the electronic device 200 may be omitted. For example, the body part 223 and the support parts 221 and 222 may be directly connected.

According to various embodiments, the body part 223 may include at least one transparent member (e.g., the first transparent member 220, the second transparent member 230), at least one display module (e.g., a first display module 214-1, a second display module 214-2), at least one camera module (e.g., a front shooting camera module 213, eye tracking camera modules (e.g., a first eye tracking camera module 212-1, a second eye tracking camera module 212-2), recognition camera modules (e.g., a first recognition camera module 211-1, a second recognition camera module 211-2)), and at least one microphone (e.g., a first microphone 241-1, a second microphone 241-2).

In case of the electronic device 200 illustrated in FIG. 2A, light generated by the display modules 214-1 and 214-2 may be projected onto the transparent members 220 and 230 to display information. For example, light generated by the first display module 214-1 may be projected onto the first transparent member 220, and light generated by the second display module 214-2 may be projected onto the second transparent member 230. Light capable of representing a virtual object is projected onto the transparent members 220 and 230 formed of at least in part a transparent material, so that the user can recognize the reality superimposed with the virtual object. In this case, the display module 160 described in FIG. 1 may be understood as including the display modules 214-1 and 214-2 and the transparent members 220 and 230 of the electronic device 200 shown in FIG. 2 . However, the electronic device 200 described in the disclosure is not limited to displaying information through the above-described scheme. The display module included in the electronic device 200 may be changed to a display module having various types of information display methods. For example, in case that a display panel including a light emitting element made of a transparent material is embedded in the transparent members 220 and 230 themselves, information displaying may be possible without a separate display module (e.g., the first display module 214-1, the second display module 214-2). In this case, the display module 160 described in FIG. 1 may refer to the transparent members 220 and 230 and the display panel included in the transparent members 220 and 230. At least one display module may include a light source module. The light source module generates light. Light generated by the light source module may be projected onto the transparent members 220 and 230 to display information.

According to various embodiments, the virtual object outputted through the display modules 214-1 and 214-2 may include information related to an application program executed in the electronic device 200 and/or information related to an external object located in the real space perceived by the user through the transparent members 220 and 230. The external object may include things existing in the real space. Hereinafter, the real space perceived by the user through the transparent members 220 and 230 will be referred to as a user’s field of view (FoV) area. For example, in image information related to the real space acquired through the camera module (e.g., the shooting camera module 213) of the electronic device 200, the electronic device 200 may identify an external object included in at least a part of the area determined as the user’s field of view (FoV). The electronic device 200 may output a virtual object related to the identified external object through the display modules 214-1 and 214-2.

According to various embodiments, the electronic device 200 may display a virtual object related to an augmented reality service together, based on image information related to the real space acquired through the shooting camera module 213 of the electronic device 200. According to an embodiment, the electronic device 200 may display the virtual object, based on the display module interlocked with user’s both eyes (e.g., the first display module 214-1 interlocked with the left eye and/or the second display module 214-2 interlocked with the right eye). According to an embodiment, the electronic device 200 may display the virtual object, based on preset configuration information (e.g., resolution, frame rate, brightness, and/or display area).

According to various embodiments, the transparent members 220 and 230 may include a condensing lens (not shown) and/or a waveguide (e.g., a first waveguide 220-1 and/or a second waveguide 230-1). For example, the first waveguide 220-1 may be partially located in the first transparent member 220, and the second waveguide 230-1 may be partially located in the second transparent member 230. Light emitted from the display modules 214-1 and 214-2 may be incident on one surface of the transparent members 220 and 230. Light incident on one surface of the transparent members 220 and 230 may be transmitted to the user through the waveguides 220-1 and 230-1 located in the transparent members 220 and 230. The waveguides 220-1 and 230-1 may be made of glass, plastic, or polymer, and may include nano-patterns formed on one inner or outer surface. For example, the nano-pattern may include a polygonal or curved grating structure. According to an embodiment, light incident on one surface of the transparent members 220 and 230 may be propagated or reflected inside the waveguides 220-1 and 230-1 via the nano-pattern and transmitted to the user. According to an embodiment, the waveguides 220-1 and 230-1 may include at least one diffractive element (e.g., a diffractive optical element (DOE), a holographic optical element (HOE)) or a reflective element (e.g., a reflective mirror).

For example, the shooting camera module 213 may photograph the front direction of the electronic device 200, and the eye tracking camera modules 212-1 and 212-2 may photograph the opposite direction to the photographing direction of the shooting camera module 213. For example, the first eye tracking camera module 212-1 may partially photograph the user’s left eye, and the second eye tracking camera module 212-2 may partially photograph the user’s right eye. According to an embodiment, the shooting camera module 213 may include a high resolution (HR) camera module and/or a photo video (PV) camera module.

According to an embodiment, the recognition camera modules 211-1 and 211-2 may detect a user gesture within a preconfigured distance (e.g., a predetermined space) and/or a predetermined space. The recognition camera modules 211-1 and 211-2 may include a camera module having a global shutter (GS). For example, the recognition camera modules 211-1 and 211-2 may be a camera module having the GS capable of reducing a rolling shutter (RS) phenomenon in order to detect and track a quick hand gesture and/or a minute finger gesture.

For example, the first light emitting device 242-1 may be disposed at a portion corresponding to the user’s left eye, and the second light emitting device 242-2 may be disposed at a portion corresponding to the user’s right eye. In an embodiment, the light emitting devices 242-1 and 242-2 may be used as auxiliary means for increasing the accuracy when photographing the user’s pupils with the eye tracking camera modules 212-1 and 212-2, and may include an IR LED that generates light of an infrared wavelength. In addition, the light emitting devices 242-1 and 242-2 may be used as an auxiliary means in a dark environment or an environment where it is not easy to detect a subject to be photographed due to the mixing of various light sources and reflected light when photographing a user’s gesture with the recognition camera modules 211-1 and 211-2.

According to various embodiments, the electronic device 200 may include a microphone (e.g., the first microphone 241-1 and a second microphone 241-2) for receiving a user’s voice and ambient sounds.
